I think you need to be careful with choosing to use CSV format. CSV works fine as long as you are not handling character stings. Character strings get messy as soon as they might introduce commas or characters outside of ASCII. For tabular

Not necessarily, imagine a port knocking monitor that stores each port attempt it sees in a large buffer. Imagine you make many attempted connections allowing you to overflow the buffer and write arbitrary data onto the heap.

It's worth reading the full technical analysis https://windows-internals.com/printdemon-cve-2020-1048/ It's well written and easy to follow even for someone that doesn't know much about Windows security.

I've always argued that if you are getting close to having to worry about underflow, overflow etc. then you have an ill-conditioned problem and just increasing the size of your intermediate results won't help you a huge amount bec

This shows the value of training and realistic simulations. The first time I gave this a go, I completely failed. If I had really been in space the mission would have failed and potentially lives lost. But I learnt a lot and the next attemp

Yes it is still advantageous to demote out of stock items in the search results. But if the store knows a certain Wunderbaum flavor is really popular but not in stock right now it should probably show up fairly highly in the search results.

And I don't consider being able to "write compilable code" as a good metric for programming ability. You can be a great programmer in many different ways: in optimising for performance, in optimising for testability, in incre

I think the fact that out of stock items aren't shown isn't a UX improvement. If an item isn't in stock and you can't see that it is normally stocked then you will probably shift your business elsewhere and not come back

Yes but (if we believe they are telling the truth) this was only done accidentally and they only intended to sniff the SSIDs. https://publicpolicy.googleblog.com/2010/05/wifi-data-collec...

Those modifications seem unlikely, You can't easily reinforce pillars in a car and they are designed to support the full weight of the car in a roll-over situation so a few 10s of kgs of equipment on the roof make little difference. Si

I agree MD5 is not broken for digest authentication. MD5 is only weak for chosen-plaintext or brute force attacks. With a correctly generated nonce, it is more than secure enough.

Well what are the issues you are currently having with Postgres 10? It doesn't sound like there is any compelling reason.

Correct, I rounded to the appropriate number of significant figures. I hate extra significant figures which suggest that the data is more precise than it really is

Has anyone used the greenarray technology for any real world applications? It seems to fit somewhere between an FPGA and a microcontroller, but it doesn't seem that obvious to me what the benefits are, maybe less power than a microcont

Thanks for the link. They assume that Android devices can scan in the background but my experience is that whilst this is theoretically achievable, the experience is unreliable in practice. See this guide which shows how to make things more

DISTINCT generally requires the results to be sorted which has O(n^2) worst performance so it can have a big performance hit on a query. It is best to make your database structure such that queries only return distinct data. E.g. by disallo

Yeah just realised you're running the algorithms in real time in the browser so makes it a bit tricky. Maybe just have them pause when they reach the end state and have to click the play button to re-run.

Really lovely animations, great for illustrating a quite complex algorithm. It would be nice to have a button to pause the animation at its end state to compare the curve shape and number of calculations.
